【英文介绍】

Allen-Bradley 1756-A17 is a component of ControlLogix. This is a 17-slot chassis that houses the ControlLogix modules, including processors, I/O modules, dedicated modules, and included partner modules.

The 1756-A17 provides the module housing, including the necessary backplane connections to allow internal modules to connect and distribute bus power through embedded electronic circuits, and provides mounting slots for the chassis. Its power consumption is 1.5A@ 1.2VDC; 4A/4A @ 3.3 volts DC; 15 A/6 A@ 15 A/6 A and 2.8 A/2.8 A@ 24VDC.

The 1756-A17 supports horizontal installation only and requires a minimum cabinet size or available space of 76.2 x 91.4 x 20.3 cm (30 x 36 x 8 inches). The 10 mounting tabs provided allow the panel to be mounted directly to the cabinet panel for quick installation. The case weighs 2.20 kg (4.8 lb).

When installing the 1756-A17 case with a nearby ControlLogix case, Specific space requirements are 10.2 cm (4.0 in) plus power supply width (left side), 7.7 cm (3.0 in) plus power supply width (right side), 15.3 cm (6.0 in) top clearance and 5.1 cm (2.0 in) bottom clearance.

The 1756-A17 was available in three chassis versions, notably the A, B, and C Series, which specifically offered improved slot orientation, ventilation, stronger mounting pads, additional holes for mounting pads, and additional ground screws for end-panel grounding.

The 1756-A17 standard chassis includes an inherent timestamp function for SOE applications. The chassis midplane distributes power to each module in the chassis by providing a high-speed communication path between modules. It requires Bulletin 1492 wiring IFM or RTB to connect all field side wiring. The 1756-A17 standard chassis has RIUP function and is easy to maintain. To prevent replacement errors, it also offers electronic keying. If any system or field failure occurs, its comprehensive diagnostic capabilities help identify the fault. It is compact, cost-effective, and easily compatible with items such as the PanelView operator.
